AutoTRAX	AutoTRAX integrates tools that include schematic capture, simulation, layout with autoplacement, autorouting and 3D visualization. Created by Kovac Software
CADSTAR	PCB design software. Free version limited to 50 library components and 300 pins. Created by Zuken.
LASI	LASI (LAyout System for Individuals) is a set of "general purpose" layout and design programs. It was not specifically designed for CMOS logic circuit layout, but most people use it for that purpose. LASI can draw schematics and can be used for most of the other graphical jobs of an IC project. Created by Dr.D.E.Boyce.
PCB123	Free schematic and layout software. Import Net lists from multiple CAD vendors, 145,000+ parts library, 2, 4, and 6 layer support, design rule check/design for manufacturing, copper pour with net connectivity. Created by PCB123
TimeGen	Allows a digital design engineer the capability to quickly and effectively draw digital timing diagrams. The waveforms can be exported to other Window programs, such as Microsoft Word, for use in writing design specifications. The "Save" and "Copy/Paste" are disabled, also limitations on the number of signals that you can add to the screen. Created by XFusion Software
